LAMP-WICK.

Specification of Letters Patent No. 23,801, dated April 26, 18159.

To all whom it may concern:

Be it known that I, JOHN B. IVORTEN- DYKE, of Godwinsville, in the count-y of Bergen and State of New Jersey, have invented a new and Improved Tick for Candles and Lamps; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification.

The invention is illustrated in the accompanying' drawing in which-- Figure l represents a piece of the wick, having one end untwisted to show its structure, and Fig. 2 represents one of the yarns of which the strands are composed, with its preparatory twist.

Similar letters of reference indicate corresponding' parts in both figures.

a, a, are the yarns, and c, c, the fine threads with which they are spun to form the strands. To produce the strands I take a sliver which has been well carded and drawn to a uniform size by any known process and spin it by any suitable machin-ery to produce what I term the preparatory twist represented .in Fig. 2, where the direction of such twist is indicated by an arrow. I afterward spin it with the tine and compact thread C', in the opposite direction to that of the preparatory twistto such a degree as to take out all the preparatory twist and leave it with such a degree of reversed twist as will be entirely or almost entirely taken out by the twisting of the strands together to produce the wick, the latter twist being in a direction the reverse of that in which strands are spun and the same as that of the preparatory twist. The object of the preparatory twist of the yarn a, is that by the process of spinning it with the fine thread c, to produce the strands, it may, by the elongation consequent upon the takingout of such twist, be caused to coil itself around the fine thread while the latter remains nearly straight, and that while thus Vcoiled and so having its {ib-ers held together by the fine thread which gives strength to the strand, it may remain in a comparatively loose condition, and when the strands are twisted together to form the wick, the said yarns a, o, may be without any or with scarcely any twist, none being necessary. The wick thus produced may, by proper attention to the spinning process throughout, including the spinning of the binding thread o, as will be readily understood, have all its fibers following' exactly the direction of the strands in the wick, and thus be made to permit an unimpeded capillary action, while it possesses more compactness than any other twisted wick known to me.

The direction of the twist or amount thereof in the binding thread c, is of comparatively little import-ance, provided its twist is such as to give it or leave it with the requisite tenacity, as the amount of fiber in it is so small compared with what is contained in the yarn a.

The wick produced in this way may or may not have a central core c, of untwisted yarn; but this forms no part of my invention. The machinery employed in twisting the strands together may be the same as that commonly employed in the manufacture of twisted wick.

I-Iaving described my invention, I claim and desire to secure by Letters Patent As an improved article of manufacture, a lamp-wick composed of strands that have received a preparatory twist in one direction, are then spun .in the contrary direction with and coiled upon a thread (0)', and are then twisted together, all as herein shown and described.
